Vanity Fair magazine and the National Security News Service claim to have knowledge "developed from first-hand sources" of a car crash that involved then-Lt. McCain at the main gate of a Virginia naval base in 1964, according to legal filings. The incident has been largely, if not entirely, kept from the public. And in documents suing the Navy to release pertinent information, lawyers for the NS News Service allege that a cover-up may be at play.

"Plaintiffs have also obtained documents showing that law enforcement officers were ordered back to the accident scene to retrieve personal physical effects. The Navy has never publicly acknowledged this information," one document reads. "This request involves federal government activity, as it addresses what may be an attempt by the Navy to protect by concealment the involvement of a former Navy officer, sitting Senator and Presidential candidate in a serious incident involving the injury or death of another human being."

The first request for information concerning duty assignment logs to Portsmouth Naval Hospital -- where McCain was allegedly brought after the accident -- came in the form of a Freedom of Information Act request on August 28, 2008. The Navy acknowledged receipt of the request and advised that it had located the relevant information a few weeks later, only to deny the FOIA on grounds that it didn't prove an "imminent threat to the life or physical safety of an individual" or satisfy the criteria of "a breaking news story of general public interest."
